As the terminal 30 having built with the NFC module 32 is placed within the range of the home appliance 10, the terminal 30 and the home appliance 10 starts the NFC communication.

Thus, a user selects the information that is to be set up at the home appliance 10 from the WIFI set-up information being used at the terminal 30 (206), and the APP installed at the terminal 30 transmits the selected set-up information, such as the SSID, the authentication method, the encryption method, and the authentication key, to the home appliance 10 through the NFC communication (208).

As the above, as the set-up information that a user selected is transmitted by the terminal APP to the home appliance 10, the WIFI module 12 built at the home appliance 10 makes an attempt to connect to the AP 40 by using the set-up information that is transmitted from the terminal 30 (210).

At this time, when an encryption is not set up at the home appliance 10, the terminal 30 APP transmits device information and device authentication key that are being input from the user to the home appliance 10 through the NFC communication (212).

As a result of the above, the set-up of the WIFI of the home appliance 10 is completed (214).

As the above, in a conventional method of setting up the WIFI of the home appliance 10, the input interface or the display apparatus configured to set up the WIFI is needed at the home appliance 10, but in the present disclosure, by using the terminal 30, the input is made possible without a separate manipulation of a user, and the AP set-up value or the device information, as well as the device authentication key are made possible to be changed.

Hereafter, referring to FIG. 6, the description will be made in relation to the operation after the home appliance 10 having built with the WIFI module 12 is set up to be connected to the AP 40 by using the terminal 30 capable of supporting the WIFI or by using the terminal 30 having built with the NFC module 32.

FIG. 6 is a flow chart showing a method of controlling the home appliance at the network system of the home appliance after the home appliance is set up to be connected to the AP 40 in accordance with an embodiment of the present disclosure.

In FIG. 6, when the power of the home appliance 10 is ON, the home appliance 10 is at standby for the WIFI connection (300), and a user executes the APP at the terminal 30 (302).

Thus, the APP at the terminal 30 makes an attempt to be connected to the home appliance 10 through the WIFI or through the NFC communication (304), and the home appliance 10 checks that the device information and the device authentication key are correct (306).

After the confirmation is made at the home appliance 10 that the device information and the device authentication key are correct, the home appliance 10 transmits the device state, the operation information, and the error information to the terminal 30 (308).

Thus, a user may be able to checks and proceed with the device state, the operation information, and the error information of the home appliance 10 through the APP at the terminal 30 (310), and in addition, through the APP of the terminal 30, the operation information of the home appliance 10 may be modified, or the home appliance 10 may be turned OFF (312).
